You should only use the battery that's for your phone. It's not meant to take a higher wattage battery, so will malfunction. It's like trying to put a v8 engine into a hairdryer if you know what I mean. 😊

I haven't read any analysis of this, but my guess would be that it would make no significant difference. Really all that it does is average out the colors of all pixels (so red green and blue of each pixel are the same rather than different strengths). Night Shift does use a little extra battery, though. Apparently it uses more energy to show the yellower ...

It makes no difference on the iPhone 6. So neither a reduction, nor extra consumption. Some sources that tell the same story: From a SuperUser question LCD/LED screens; how color affects the power consumption?: Conventional LCDs and LED based LCDs consume power that largely depends only on the intensity of backlight. This means to save power you want ...

This is usually for one of two reasons: Defective battery. Your 6S is less than a year old, so contact Apple's support for your country for a replacement. Usually if this is the case, it will always happen at the same percentage because of one or more defective cells in the battery. Bad calibration. I've never seen that be 30% off, though. After the ...

I finally fixed it today. It turns out the Magsafe DC-in board can be replaced. It's a little $25 part ($15 refurbished). I followed the instructions on iFixit.com; you have to take apart practically the whole laptop which includes a lot of tiny, tiny connectors, but it's doable with just a few screwdrivers and a spudger I made from a chopstick. The ...

Unfortunately, there is no direct way to force OS X to use battery-power mode (here, here and here). OS X uses Intel Speedstep which changes the P-state of the processor depending on the computer's power status (AC/battery). AFAIK, the only thing you can do is set your AC mode power management settings to the same as battery mode. Using pmset, you can see ...

The 12.9" iPad Pro can use power faster than the 12W power adapter can supply it. That's why it can run out of power when running for example a game, even though it is connected to the charger. To avoid that, use the 29W Apple power adapter instead. The 29W adapter is not supplied with the iPad Pro, but must be bought seperately.

The reason is because when you connect an external display, even if you close the laptop and use it in clamshell mode, the laptop automatically switches from an integrated video card (this uses much less power) to a more powerful, discrete video card (this uses a lot of power). This is also true regarding Intel Iris Graphics, which has different power ...

Keeping your Mac plugged in 24/7 is dangerous and will shorten the life of your battery exponentially. From imploding to starting a fire, you should only plug it in when needed. A while back I lost everything when I left my Mac (which was bought recently) plugged in for the week I went to Italy. The battery imploded and I was unable to retrieve anything. For ...

No, not at all. I leave my MacBook Pro connected to the charger for days on end sometimes and the battery still works fine. Once the battery gets to 100%, if it is still connected to the charger the MacBook stops charging the battery automatically and allows the battery to go down to 97%, then allows the battery to charge back to 100%, and repeats that cycle ...

Apple recommends not leaving it plugged in all the time. This can damage the battery over time, as lithium-ion batteries need to be frequently discharged. If you are going to use an external monitor, why not buy a desktop computer? MacBooks are made to be portable and have their batteries used.

You battery is dying! 4 years is usually average when a battery starts dying. I would personally take it to the Apple store, have them look at it. They will tell you if it needs replacing. I would just get it replaced at the Apple store, the price difference is not to much and you know you're getting a good battery. Replace it ASAP, as there is a chance ...

The short answer is YES Apple is going to use different part numbers but essentially they are the same battery. The easiest way to see if the batteries are interchangeable is to take a look at the aftermarket battery replacement. For example, this particular battery made by GreenBox Innovations and found on Amazon fits Macbook Air Models from Late 2010 ...

Your battery is shot. A battery's life is determined more by age than the number of cycles. Yes, number of cycles do play a part, but the biggest culprit is age. In short, you have a 4 year old battery. A 4 year old battery that was never used is going to perform about as well as a 4 year old battery with 500 cycles. MATH FINDS TOP CULPRIT AS ...

There's also a third party app BattMan, which can raise Notifications via Notification Centre and sound an audible alarm when the battery charge drops to certain percentage or time left on battery reaches a certain level (both user settable). Full Disclosure: I'm the dev behind this app.

Default Warning The battery indicator in the menu bar will turn red when the battery is low. There will also be a critical low power warning when the computer needs to emergency shut down. See Apple's About Mac notebook batteries page, in particular this section: The low battery warning doesn't display If you don't receive a warning when your ...

In one circumstance, a force quit can have a benefit to iOS that outweighs the cost of more processing needed to clean up the process, restart it, and purge any files that are cached/open. The negative to doing this is that apps don't run in the background - so once you switch to a new app or the springboard / list of icons / lock screen - iOS has already ...

You can keep your Mac on forever when you need to (including while AirPlaying) without digging into settings if you download the Mac app Caffeine. With Caffeine, a coffee mug will appear on your Mac's menu bar. Just click it to prevent your Mac from sleeping indefinitely, and click it again to allow it to sleep. This is a very simple method of keeping your ...

I had this problem with my MBP and iMac 5K (wake up in sleep mode automatically. It was actually the Google Drive app's fault; after I removed it, the problem was solved.

Try something like this: https://itunes.apple.com/us/app/amphetamine/id937984704?mt=12 With just a click you can keep the display on for a set or indefinite amount of time.

Theoretically, yes. Apps running at background do consume memory (their threads still exist and that's why you can see them listed when you double click the Home button), and thus they do consume battery. But practically, not really. iOS does a fairly good job on memory management, and apps running at background only consume a small amount of memory. And ...

I have found that ending the Facebook app in particular can save battery life. After checking its usage in the battery section (Settings > Battery > Time), I can't help but be convinced that it's not playing nice.

There's been much debate and discussion around this topic. I believe it was beneficial for iOS back in the v3 and v4 days but now it's not. Craig Federighi even came out recently saying it's not necessary and it doesn't increase the battery life. Apple has built-in their memory management the proper time to suspend and/or kill an app when necesssary. The ...

It turns out my problem is related to a bug in versions 9.9 and 9.91 of JAMF (enterprise management software) as described here: https://jamfnation.jamfsoftware.com/discussion.html?id=19626 It's unclear as to whether it's directly related to El Capitan or if it affects all versions of OS X. As far as I know, this bug in JAMF has not been resolved yet but I ...

Yes, running Ubuntu natively (dual booting) may be a better way, but you will lose all "pros" of your MacBook Pro 2015 (Mac OS X). There is another way of "using Ubuntu," which is Docker. I bet you have heard of it, but you may not know that the latest Docker beta uses a native virtualization mechanism, and it does not need VirtualBox, or any other virtual ...

Booting Ubuntu on a dual boot partition has a similar battery life to OS X, perhaps slightly shorter, due to less efficient optimization for the MacBook Pro's hardware. In a virtual machine, despite lots of "clever" optimizations and CPU hardware virtualization features, there are two complete operating systems, with two kernels, and two display managers* ...
